The average velocity of the lizard for the whole journey is 0.26 m/s Down.
<h3>What is average velocity?</h3>
The term average velocity has to do with the velocity of the lizard for the whole journey. We can see that the downward displacement is greater than the upward displacement.
Thus;
Velocity = displacement / time = 23.7 m - 15.5 m/31.5s = 0.26 m/s Down.
Thus, the average velocity of the lizard for the whole journey is 0.26 m/s Down.

Answer:
v=39.05 m/s
Explanation:
Given that
x= 56 cm
F= 158 N
m= 58 g = 0.058 kg
Lets take spring constant = k
At the initial position,before releasing the arrow
F= k x
By putting the values
F= k x
158= 0.56 k
k=282.14 N/m
Now from energy conservation
Lets take final speed of the arrow after releasing
k x²=mv²
282.14 x 0.56² = 0.058 v²
v=39.05 m/s
Answer:
Electron.
From plastic rod to metal sphere.
Explanation:
The charged plastic rod is negatively charged, which means it contains excess electrons.
After they touch each other, the plastic rod now has a more positive value.
Since the sphere is a metal sphere, it is able to conduct the flow of electrons.
Hence, the plastic rod has given off some of its electrons to the metal sphere.
V=IR
i= V/R
I=5/15000
I= 0.3 mA
